Detailed explanation-1: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.
Detailed explanation-2: -The nucleolus is a ribosome production factory, designed to fulfill the need for large-scale production of rRNAs and assembly of the ribosomal subunits.
Detailed explanation-3: -The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell.
Detailed explanation-4: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
Detailed explanation-5: -The main function of nucleolus is to produce and assemble subunits which form the ribosome. Ribosome is the site for protein synthesis. Nucleolus plays an indirect but crucial role in protein synthesis by assembling the ribosome subunits.
